A threshold question prevents our proceeding directly to Northeastern's Sherman Act claims. Appellants assert that the design of the protective coupler cannot be attacked on antitrust grounds because implementation of the coupler requirement was subject to review by the Federal Communications Commission.^[7]It is to this issue that we now turn.

Appellees claim no explicit exemption; it is on a more elusive defense that they base their parry: "implied immunity." This principle represents an effort to resolve the inherent conflict between the Sherman Act's mandate of robust competition and the "public interest" standard underlying governmental regulation of business activity. The touchstone of this analysis is Congressional intent,seeOtter Tail Power Co. v. United States,410 U.S. 366, 93 S.Ct. 1022, 35 L.Ed.2d 359 (1973),since the principle is founded on the notion that, in some circumstances, a Congressional delegation of regulatory authority carries with it the implication that the antitrust laws shall not apply to the conduct thus regulated. There are two narrowly-defined situations in which "repeal" of the Sherman Act will be inferred:

Question 11

What is the ideal management for scorpion bite?

Question 12

In acute anaphylaxis, you recommend IM adrenaline (epinephrine).

Surely in such an acute situation intravenous adrenaline would

be better?

Question 13

Why should patients avoid grapefruit juice if they are taking

terfenadine?

Question 14

Many older drug therapies, e.g. penicillin in streptococcal sore throat,

have never been submitted to rigorous trials such as a randomized

controlled trial (RCT). Do you think they should be?

Question 15

Please explain why some drugs are teratogenic in the first trimester and

some in the second?

Question 1616

What is the difference between compliance and concordance?

Question 17

The rates of paracetamol (acetaminophen) self-poisoning have decreased

in the UK. Why is this?

Question 18

Is N-acetylcysteine of any use in a case of paracetamol overdosage taken

16 hours previously?

Question 19

What is meant by primary end point and secondary end point?

Question 20

Can chronic exposure to organophosphorus compounds (in farmers)

cause axonal radiculoneuropathy persisting for years? Is this disease

reversible?
